Added #

• Auto-registration system: Simplified API with automatic parser registration
• SheetMapperRegistry: Central registry for managing sheet mappers
• Generated init functions: Auto-generated init<ModelName>SheetMapper() functions for easy initialization
• Cleaner widget API: Removed the need for parser parameter in SheetMapperWidget

Changed #

• Breaking Change: SheetMapperWidget no longer requires a parser parameter
• Breaking Change: Models now use with $ModelSheetMapper instead of with _$ModelSheetMapper
• Simplified initialization process - just call generated init function once in main()
• Updated documentation with cleaner 4-step getting started guide

Migration Guide #

From 1.0.0 to 1.1.0

1. Remove the parser parameter from SheetMapperWidget:

   // Before
   SheetMapperWidget<User>(
     parser: User.fromSheet,
     onResult: (users) => print(users),
     onError: (error) => print(error),
   )
   
   // After
   SheetMapperWidget<User>(
     onResult: (users) => print(users),
     onError: (error) => print(error),
   )
   

2. Update your model to use the new mixin name:

   // Before
   class User with _$UserSheetMapper { ... }
   
   // After
   class User with $UserSheetMapper { ... }
   

3. Add initialization in main():

   void main() {
     initUserSheetMapper(); // Add this line
     runApp(MyApp());
   }
   

4. Regenerate code:

   dart run build_runner build --delete-conflicting-outputs
